Challenges sufficiency of 12-hour caffeine abstention for adenosine scintigraphy; leaves open optimal protocols or verification methods.
Does a 12-hour abstention from caffeine ensure adequate caffeine clearance and prevent symptom attenuation during adenosine myocardial perfusion scintigraphy?
A 12-hour abstention from caffeine may be insufficient prior to adenosine myocardial perfusion scintigraphy, as 74% of patients still had measurable caffeine levels which significantly attenuated clinical symptoms during the test.
